The ThumbRail is a long thumb rest for a bass guitar that runs the length of the right hand playing surface (neck to near bridge) allowing for an endless amount of tone variation with a comfortable and familiar hand position. This eliminates the tone-limiting "thumb on the pickup" locations or hand stretching to get where you want to be to get the right tone and attack. Just play.
Secures at standard pick guard screw locations using your existing screws, making it an easily reversible update to your bass.
This unit is designed specifically for the Fender Geddy Lee Artist Series Jazz Bass. It may fit others, but has only been tested on the Geddy Lee model.
Note, due to the length of the rail and finishing capabilities, when ordering in plastic, this is only available in NON-polished black and white "Strong & Flexible". Due to that, it has a textured surface. This ads some grip which keeps your thumb in place nicely.
Also note, there has been three modifications to the design since this product photo was taken. The string side has been rounded just like the top side to eliminate your fingers hitting what was the cornered edge. Also, the neck-side screw hole has been lowered for the same reason. Lastly, to provide tactile thumb positioning indicators, indexing marks have been added on the top-side at the neck end, and over each of the front side of the pickups.
